Good day to you Andrew, 
 With the information provided above, no one will be able to answer this questions without a lot more details. Suggest that you build your model in AutoPIPE and send necessary values of displacement per load case to an Flexible Joint manufacturer. The will make some suggests for your to consider, model these Flexible Joints in AutoPIPE with the proper settings, and run an analysis to see if the flexible joints settings and locations minimize the stress in the system to your satisfaction.
